Presentation
This project is interested in electronic documents, such as technical
documentation, hypertext, and multimedia. It studies document models that
take into account logical structures, graphical presentation and multimedia
contents. It also develops editing techniques based on these models.
OPERA is a project ofthe research unit
Rhône-Alpes of INRIA.
Project Opera was closed at the end of 2002. Some of its activities are
continued in project WAM.
Topics
- Models for multimedia structured documents
- Models that can represent different types of documents in a
homogeneous way, including structured documents, hypertext and
multimedia. A major activity in this area concerns transformation
techniques required for XML
structured documents. Another activity focuses on the specification
of generic models for multimedia documents.
- Edition/presentation of multimedia documents
- Authoring and presentation environments
for multimedia documents based on a representation of time well adapted
to an incremental verification of temporal scenarios.
- Cooperation on the Web
- Cooperative document editing and the impact of new web technologies
for the emergence of cooperative tools on the web.
Software
Current project
- Kaomi
- A toolbox for creating authoring environments for multimedia
documents
- Madeus-Editor
- An authoring environment for multimedia documents specified with
flexible relations.
- SMIL-Editor
- An authoring environment for multimedia documents specified in the
standard SMIL1.0.
- Mdéfi
- An authoring and presentation environment for multimedia documents in
which the internal structure of complex media such as video can be
edited to be used inside spatial and temporal synchronisations in the
document.
- LimSee
- A temporal editor for multimedia documents specified in the standard
SMIL1.0.
- PocketSMIL
- An embedded SMIL player written in C++, well suited to PDAs and other
mobile devices.
Previous projects
- Thot
- a structured document editor, used for a number of experiments such
as active documents, embedding complex physical structures in logical
structures, transformations of logical structures, Web editing,
etc.
- Byzance
- a cooperative structured editor
Utilities
- MathMLC2P
- An XSLT transformation which translates MathML 2.0 content
markup into Presentation markup
W3C at Inria Rhône-Alpes
The project OPERA has close relationships with the W3C Inria Rhône-Alpes team. The W3C browser/editor Amaya is based on the Thot toolkit..
